Bandwidth of a truck

It took almost 24 hours to sync my music collection to the USB drive on my laptop over WiFi. It seems the combination of network and drive keeps the PC quite busy servicing interrupts even if it's not actually doing much. I wanted to take some films with me but the multi-gigabyte transfer across the air didn't appeal. In the end I used my second (somewhat beefier) usb drive to transfer them downstairs. I also cleared a 10's of gigabytes out of my home partition in the process.
